Ever since I was a teenager, I've worn gloves specifically to keep from grinding crap into the palms of my hands. In practice, I fall very rarely and keep my hands on the bars when I do.
Today, I chose not to wear gloves which is weird because I always insist on them. So of course, I fell and ground crap into my hands.
Add to that a fall because I couldn't clip out (in frogs -- the easiest system on the planet) and this was a banner day.
To add insult to injury, my front shift cable broke right away which made the hilly section loads of fun. It's definitely been one of those days.
